What to do
Operators of Airbus A350-941 and A350-1041 aircraft with affected RAT modules must replace these parts with serviceable ones within four years from 10 November 2025, following Airbus Service Bulletin A350-24-P149. Maintenance teams must cease using the previous maintenance procedure task for RAT retraction from the effective date and must not install any affected RAT modules on aircraft after replacement or from the effective date for unaffected aircraft.
Summary
EASA Airworthiness Directive 2025-0238 is a corrective directive addressing the replacement of the Ram Air Turbine (RAT) module on Airbus A350-941 and A350-1041 aeroplanes. It targets RAT modules identified by Part Number 1713586A that have been deployed and retracted in flight, due to corrosion issues affecting electrical power generation. This directive applies to all manufacturer serial numbers of the specified Airbus A350 models.
What changed
This directive introduces a mandatory replacement of affected RAT modules within four years of the effective date to prevent corrosion-related failures. It also prohibits maintenance actions using the previous maintenance procedure task and bans the installation of affected parts on any aircraft. The directive corrects a typographical error from its original publication.
Why it matters
This directive is critical for maintaining the reliability of the RAT electrical power system, which is essential during emergency conditions. Operators and maintenance organizations must ensure compliance to avoid potential partial or total loss of RAT power generation, which could compromise aircraft control. Compliance ensures continued airworthiness and adherence to European Union aviation safety regulations.
